FIELD OF THE DISCLOSURE

The disclosure relates to the field of rolling curtain technologies, and more particularly to a rolling curtain mounting housing and an electric rolling curtain.

BACKGROUND OF THE DISCLOSURE

With the progress of science and technology, the use of electric rolling curtain has become quite common now, which has brought convenience to users to a certain extent. Electric rolling curtain motors can be divided into four types according to power supply modes. A first type is an alternating current (AC) powered curtain motor, which has high power and high horsepower, but has high power consumption, large noise and vibrates greatly and does not save energy; and moreover it can only be used for straight tracks and is mainly used in engineering. A second type is a direct current (DC) powered curtain motor, which has small volume, low vibration, low noise, low power consumption, but excessively low horsepower, and thus it is mainly used in homes and hotels. A third type is a battery powered curtain motor, which is powered by an ordinary dry battery, energy-saving and environment-friendly. A fourth type is a solar powered curtain motor, which is powered by solar cells, and the power comes from solar energy.

As to an existing battery powered curtain, a battery therefore is generally installed in a motor, which makes it difficult to replace the battery. If the motor is damaged, the whole power supply system cannot be used. For example, a Chinese patent (Publication No. CN203978251U) discloses a structure in which a battery is installed in a motor. Referring to FIG. 1 , as to the curtain where the battery is installed in the motor, a roller 30 of the curtain is arranged in a shaft sleeve 20, the motor is arranged in the roller 30, a power supply module 50 includes a battery pack, and the battery pack is integrated into the motor 40. However, because a movable curtain group of the curtain would be opened or closed almost every day, the power consumption of the battery is quite fast. The structure that the battery is installed in the motor is very inconvenient to replacement of the battery, and when the battery is replaced, the motor needs to be disassembled and replaced as a whole, which is extremely inconvenient to use.

The terms “installation”, “an end”, “another end” and similar expressions used herein are for illustrative purposes only.

Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the related art. The terms used in the description herein are only for the purpose of describing specific embodiments and are not intended to limit the disclosure. The term “and/or” as used herein includes any and all combinations of one or more related listed items.

Referring to FIGS. 2-25 , an embodiment of the disclosure provides an electric rolling curtain, which may include a rolling curtain mounting housing 1, an electric rolling curtain control box 2 (also referred to as control box), a motor assembly 3, an accumulator 5 (also referred to as battery), a roller 4 and a curtain body 6 wound on the roller 4. A motor is arranged in the motor assembly 3, and the accumulator 5 is configured to be installed in an accumulator compartment 1111. The rolling curtain mounting housing 1 may include a housing body 11, and the housing body 11 may include an accumulator installation part and a housing extension part connected with each other. The housing extension part extends outwards relative to the accumulator installation part, that is, the housing extension part extends towards another end not connected to the accumulator installation part. The accumulator installation part is disposed with the accumulator compartment 1111, the accumulator compartment 1111 is disposed with an accumulator placement opening, and the accumulator is inserted into the accumulator compartment 1111 through the accumulator placement opening. The electric rolling curtain control box 2 is arranged at an end of the accumulator installation part away from the housing extension part and outside the accumulator compartment 1111. The rolling curtain mounting housing 1 and the motor assembly 3 are installed on a same side of the electric rolling curtain control box 2. An end of the electric rolling curtain control box 2 is connected to the accumulator compartment 1111, and another end of the electric rolling curtain control box 2 is connected to the motor assembly 3. At least one end of the roller 4 is hollow, the motor assembly 3 is located outside the accumulator compartment 1111 and is capable of being inserted into the roller 4. When the motor assembly 3 is working, it can drive the roller 4 to rotate relative to the rolling curtain mounting housing 1, and the curtain body 6 is capable of extending and retracting under a rotation of the roller 4.

The rolling curtain mounting housing 1 provided in the illustrated embodiment can also be referred to as a rolling curtain cover, the accumulator compartment 1111 can also be referred to as an accumulator mounting compartment, and the housing body 11 can also be referred to as a cover body.

Referring to FIGS. 17-20 , in an embodiment, the housing body 11 (cover body) may further include a top baffle 13 and a front baffle 14. The top baffle 13 is configured to connect and fix the whole rolling curtain with the outside, an end of the top baffle 13 is connected to a side of the housing body 11 (cover body), and an upper end of the front baffle 14 is connected to the housing body 11 (cover body). The top baffle 13, the housing body 11 (cover body) and the front baffle 14 are sequentially connected to form a semi-enclosed mounting cavity 15 in that order, and the mounting cavity 15 is configured to accommodate the roller 4. The roller 4 is arranged in the rolling curtain mounting housing 1 (rolling curtain cover), and a motor is arranged in the roller 4. The mounting cavity 15 formed by a sequential connection of the top baffle 13, the housing body 11 (cover body) and the front baffle 14 not only provides an accommodation space for the roller 4 of the rolling curtain, but also the front baffle 14 shields an internal structure of the housing body 11 (cover body), making the overall appearance of the rolling curtain simpler and more beautiful. By setting the accumulator compartment 1111 (accumulator mounting compartment) on the cover, an independent accommodation space is provided for the accumulator 5. When the accumulator runs out, only the accumulator 5 needs to be replaced without replacing the motor, which makes the later maintenance of the rolling curtain more convenient and saves the maintenance cost.

Referring to FIG. 17 , in an embodiment, there are two end mounting seats 2 a at two ends of the rolling curtain mounting housing 1 (rolling curtain cover), an end mounting seat 2 a close to an end of the accumulator compartment 1111 can be an electric rolling curtain control box 2 with an internal circuit.

Referring to FIGS. 19-21 , in an embodiment, the rolling curtain mounting housing 1 (rolling curtain cover) is integrally formed. The rolling curtain mounting housing 1 (rolling curtain cover) is a profile material with an opening on a side. The profile material is formed with a profile cavity 113, and a part of the profile cavity 113 forms an accumulator compartment 1111 (accumulator mounting compartment). A stop block 114 is arranged in the profile cavity 113, and a distance between the stop block 114 and the end mounting seat 2 a (electric rolling curtain control box 2) matches a length of the accumulator, so that the accumulator can be fixed into the accumulator compartment 1111 (accumulator mounting compartment). The housing body 11 (cover body) is disposed with a recess, and the top baffle 13 is located above the recess to form the profile cavity 113.

Referring to FIG. 22 , in an embodiment, the accumulator compartment 1111 (accumulator mounting compartment) is disposed with a first opening 121 and a second opening 122. The opening of the first opening 121 faces an operating surface, and the operating surface is a plane of the front baffle 14. The opening of the second opening 122 faces a side mounting surface, which is the plane of the end mounting seat 2 a of the rolling curtain. The first opening 121 is an accumulator placement opening for accumulator replacement during later maintenance, the opening of the first opening 121 faces the plane where the front baffle 14 is located, which is convenient for the user to replace the accumulator from the front of the rolling curtain. The second opening 122 is configured to connect the accumulator and the motor in the motor assembly, the opening of the second opening 122 is arranged towards the plane where the end mounting seat 2 a of the rolling curtain is located, so that the circuit connecting the accumulator and the motor can be hidden on a side surface of the rolling curtain housing 1, so as to avoid the circuit from being exposed and easy to be damaged, and make the appearance of the rolling curtain more concise and beautiful. The end mounting base 2 a near one end of the accumulator compartment 1111 is the electric rolling curtain control box 2 with the internal circuit, which is disposed with a motor power interface and an accumulator interface, and the motor power interface and the accumulator interface are connected through a line, which is hidden in the electric rolling curtain control box 2. When the accumulator is connected to the accumulator interface and the motor is connected to the motor power interface, the accumulator is connected to the motor and supplies power to the motor.

The electric rolling curtain provided in the illustrated embodiment realizes the electrical connection between the accumulator and the motor assembly 3 through the electric rolling curtain control box 2 outside the accumulator compartment 1111, and sets the motor assembly 3 outside the accumulator compartment 1111, which can make the motor thin and short, more convenient for the production of the motor and reduce the cost. At the same time, after thinning the motor, it can also better realize the preparation of short curtain, reduce the restriction of long motor on the length of rolling curtain rod, realize that the electric rolling curtain can be applied to smaller windows, and expand the application market of electric rolling curtain.

Referring to FIG. 16 , the electric rolling curtain provided by the illustrated embodiment includes the following states:

S1 is the initial state of accumulator replacement, the curtain body is reset, and the end 61 of the curtain body is located at the initial position;

S2 is the retracting state during operation, the end 61 of the curtain body is located at the first position;

S3 is the extending state during operation, and the end 61 of the curtain body is located at the second position; and

when the electric curtain is working, the end of the curtain body is located at the first position or the second position. There is no sequential relationship between the retracting state and the extending state in the illustrated embodiment. In the process of use, it can be from the extending state to the telescopic state, or from the extending state to the retracting state, which is not specifically limited.

When the electric rolling curtain is working, the accumulator 5 will need to be replaced. When the accumulator 5 is installed in the empty accumulator compartment 1111 and connected to the motor assembly 3, the curtain body will automatically reset. That is, in the initial state of accumulator placement, the curtain body automatically resets, and the end of the curtain body is located at the initial position. That is, each time the accumulator 5 is replaced, the curtain body will automatically reset so that the end 61 of the curtain body is located at the initial position. After the accumulator is replaced, the end 61 of the curtain body is located at the initial position, the electric rolling curtain is at the working state, and the curtain body at the working state may be retracted or extended. In the retracting state during operation, the end of the curtain body is located at the first position. In the extending state during operation, the end of the curtain body is located at the second position, and both the first position and the second position are lower than the initial position. That is, when the electric rolling curtain is working, the end of the curtain body is always lower than the initial position.

The electric rolling curtain provided in the illustrated embodiment can automatically reset the curtain body to a higher position and correct the retracted position of the curtain body every time the accumulator is replaced. It solves the problem that the curtain body is pulled artificially in the process of use, resulting in that the curtain body cannot be fully retracted, and also solves the problem that the position of the curtain body gradually shifts in the process of use.

The electric rolling curtain provided by the illustrated embodiment, in the working state, the highest position at which the curtain body can be retracted is lower than the reset initial position, which can avoid that each retracted position is higher in the working process, which may cause the rolling curtain to separate from the roller. At the same time, it can also avoid the problem of high-power consumption due to the high retracted position each time in the use process. When the accumulator is replaced each time and the curtain body is reset, the end 61 of the curtain body is located at the initial position closer to the top of the roller 4. It can correct the position offset of the electric rolling curtain, and the user experience is good.

In an illustrated embodiment, when the end of the curtain body is located at the first position, the end of the curtain body is lower than the bottom of the roller. Alternatively, when the end of the curtain body is located at the first position, the end of the curtain body is flush with the bottom of the roller. In the working state, the curtain body can cover the side surface of the roller even if it is completely retracted. It can make the side surface of the roller not be observed by the user during the use of the electric rolling curtain, and the aesthetics is better.

In an illustrated embodiment, a position sensor is arranged on the roller 4 to sense whether the end of the curtain body is located at the initial position. In the initial state of accumulator replacement, the curtain body performs rolling reset. When the position sensor is sensed that the end of the curtain body is located at the initial position, the curtain body stops retracting and the reset is completed.

In another illustrated embodiment, there is a gap between the roller and the rolling curtain mounting housing. The diameter of the end of the curtain body is greater than the gap, so that the end of the curtain body is limited outside the gap. In the initial state of accumulator replacement, the curtain body is retracted and reset. When it is sensed that the resistance of retraction is greater than the preset value, it indicates that the end of the curtain body has been limited to outside the gap and cannot continue to retract. At this time, the curtain body stops retracting, and the end of the curtain body is located at the initial position.

Referring to FIG. 2 , in an illustrated embodiment, the rolling curtain mounting housing 1 is further disposed with a cover plate 12, which is configured to close the accumulator placement opening. When the cover plate 12 closes the accumulator placement opening, the cover plate 12 covers the side surface of the extension of the housing on the same side as the accumulator placement opening. In the illustrated embodiment, the accumulator compartment 1111 and the housing extension are covered by the cover plate 12 at the same time, so that the rolling curtain mounting housing 1 has stronger integrity and better aesthetics. Referring to FIG. 21 , in another illustrated embodiment, an accumulator compartment sealing plate 113 a is arranged on the rolling curtain mounting housing 1 (rolling curtain cover), which can avoid easy damage of the accumulator due to exposure, and can prevent accidents caused by the accumulator separating from the accumulator compartment 1111 (accumulator mounting compartment) during use.

Referring to FIG. 2 , in an illustrated embodiment, an end of the cover plate 12 is hinged to the accumulator installation part and the housing extension part, and another end of the cover plate can close or open the accumulator placement opening. In the illustrated embodiment, it is easier to open and close the cover plate 12 through the hinge of the cover plate 12.

Referring to FIGS. 3-6 , in an illustrated embodiment, the housing body 11 is formed with a profile cavity 113, the opening of the profile cavity 113 is on the same side as the accumulator placement opening. The profile cavity 113 is disposed with a stop block 114, the stop block 114 is configured to separate the accumulator installation part from the housing extension part. The profile cavity 113 of the accumulator installation part forms the accumulator compartment 1111, and the profile cavity of the housing extension part forms a non-accumulator compartment.
